Steam recovery issue in phenol tanks
Thread Content
To handle the recovery of oil and vapor from the storage tank containing crude phenol, a byproduct of coal gasification, it should be noted that phenol tends to crystallize. The tank is kept at a temperature of 50–60°C for storage, with the concentration of vaporized steam at 53 g/m3. Initially, condensation plus adsorption was considered as a solution; condensation is carried out at 40°C. However, there is a concern that temperature fluctuations could cause phenol to crystallize and thus block the adsorption material. Moreover, the operating costs of the condensation units amount to several million per year, which makes this approach uneconomical. Do any experts have any better technical suggestions regarding steam recovery from phenol tanks? Thank you!
What about solvent absorption?； Or it can be regenerated through alkali water absorption, but it’s a bit wasteful
